BURNER.

Specification of Letters Patent.

Patented Sept. 10, 1907.

Application filed November 6, 1905. Serial No. 286,158.

To all whom "it may concern:

Be it known that I, SAMUEL TULLY WILLsoN, a citizen of the UnitedStates, residing at Denver, in the county of Denver and State ofColorado, have invented certain new and useful Improvements in Burners;and I do hereby declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same.

' This invention relates to improvements in burners and moreparticularly to incandescent gas burners.

It is the object of the invention to provide a burner which is soconstructed as to give a flame a helical, whirling or gyrating movement.

With this and further objects in view, the invention comprises certainnovel constructions, combinations and arrangements of parts as will behereinafter described and claimed.

In the accompanying drawing: Figure 1 is a perspective view of thepreferred style of the deflecting device used in my improved burner forgiving a rotary, whirling or helical movement to the flame. Fig. 2 isthe top plan view of the same. Fig. 3 is a side elevation of saiddeflector or baflie. Fig. 4 is a view partially in section and partiallyin elevation showing said device in position as preferably placed whenused in connection with an incandescent burner of the ordinary type.

The present invention is designed to provide a burner, preferably a gasburner of the incandescent mantle type, with means for imparting to theflame a whirling, helical or gyratory movement. In constructing a burnerfor ordinary illuminating or fuel gas with this object in view, asuitable mixing tube or Bunsen burner (1) may be employed, the mixture"of air and gas being preferably delivered therefrom into a preferablycylindrical member (2). Mounted within said member (2) may be placed ascreen (3) and above the screen, if one be used, is an extended portion(4) of member (2) carrying the baffle or deflecting device (5). The useof my device is not, however, restricted to the burners of the classdescribed but may be used with any kind of a burner in which thecombustible substance used is gaseous or fluidal and is under pressureor is forced or drawn through the burner or some part thereof. Inconstructing any such burner with this object in View, I interpose mydeflector in the path of the gas, fluid or flame.

The deflector is preferably constructed by forming a disk, plug or othersuitable obstruction movable or stationary in the conduit through whichthe gas, fluid or flame passes, at the desired point therein therebyforming a substantial closure of said conduit except for certain holes,openings or apertures which are formed in said disk, plug or obstructionin such shape and at such angles that the gas, fluid or flame in passingthrough said holes openings or apertures is forced to take on awhirling, helical or gyratory motion. A simple and preferable manner offorming this deflector is by cutting a circular blank with a series ofinwardly extending notches or cuts as at (7) so as to produce segmentalshaped arms or wings, the edges of which are turned at an angle to theplane of the original disk in such a way as to make holes, openings orapertures similar in construction and appearance to those in theordinary screw propeller or electric desk fan. The outer parts of thedeflector may be bent upwardly from the central portion 8 so as to givean approximately conical shape to the device. The device, because of itspeculiar construction as above described, lets portions of the gas,fluid or flame pass through said holes openings or apertures as a seriesof whirling or gyrating flames.

In the construction of the ordinary incandescent mantle burner, withthis device, the mantle (6) of the burner extends downwardly over theextended portion (4) of member (2) so that the flames are let upwardlyand spirally within the mantle.

In the specific construction of the extended portion 4 it will beobserved that the same is in the nature of a yoke and comprises ahorizontal portion employed to support the deflector, and a pair ofdownwardly extending arms having a detachable engagement with the upperportion of the mixing tube, and serving to support the before mentionedhorizontal portion. The deflector thus placed distributes the flamesover the inner surface of the mantle and the peculiar construction ofthe deflector as above-described gives a spiral direction to the flamesmaking a gyrating flame.

It will be evident that the edge cuts in the deflector of the propellertype may be of different widths so as to produce openings of differentsizes, changes in the exact widths of the openings not changing thespirit of the invention. It will be evident that the exact number of theholes, openings or apertures and the exact shape of and distancesbetween the same may not be the same at all times or under allconditions but the number, size, angle of and distances between saidholes openings or apertures may be varied to suit the nature of thecombustible material used, the pressure under which it is delivered andother varying conditions. It will also be evident that the deflector maybe constructed solidly with other parts of the burner as well as in theform of a separate part. It is also evident that in case the cone shapeddevice is used, the vertex of the cone may be upwardly or downwardlyturned.

Having now described my invention, what I claim as new and desire tosecure by Letters Patent is: I

1. A deflector for gas burners, comprising a mixing tube, and aninverted conical shaped baflle member supported over the mouth of themixing tube, the inclined sides of the battle member comprisingsegmental shaped arms which are twisted at angles to each other andhaving their edges overlapping.

2. In a burner, the combination of a mixing tube, a yoke fitting overthe discharge end of the mixing tube, and a conical shaped bafl lemember supported by the yoke, the inclined sides of the conical shapedbalfie member comprising segmental arms twisted at angles to each other.

3. In a burner, the combination of a mixing tube, a yoke comprising ahorizontal portion and downwardly extending arms having a detachableengagement with the mixing tube and serving to support the saidhorizontal portion, and a baflie member supported by the horizontalportion of the yoke, the said bafile member having a conical shape, andthe inclined sides thereof comprising segmental arms twisted at anglesto each other.

In testimony whereof I affix my signature in presence of two witnesses.

SAMUEL TULLY WILLSON.
